ROTARY iNTEBNAIfconBns-TION ENGrNE. w

Be it known that I, FREDERICK WrLF-RED GOYETTE, a citizen lof Canada,residing ati Los Angeles, in the county of Los AngelesA and State ofCalifornia, have invented anew and useful Rotary Internal-CombustionEngine, of which the following is a speciii cation.

It' is of the provide an'iinprove'd practical internal c0in-.

ustion engine in which the eX ansive force' is applied to immediatelyimpe a'rotary eleansinn4 may be taken; -to guard against eakage of' the-expanding medium; to provide for ready reversal ,of the engine; to-

make 'provision for v readyE stopping and starting of the engine, andalso to provide for impeding the engine with cushion means for thepurpose' of .holding back automobiles and like vehicles on hills,without'recourse to a brake.

This engine-is designed to v'be' sup lied -with compressedexplosiv'egas, and sue gas' may be suppliedby any form of compressor eitherdrivendirectly by the engine or by.

separate motive power, or J in some instances the engine may be o eratedb coinpressed gas fed from a ho der in W ich it .maybe contained fortransportation or storage). Y

t t \v Anobjec 'of the' invention is toprovide for the delivery fromvthe compressedassupplying device to the eplqson; cham er, of appropriateClmrges "Ofli'asfv .fmfl t0' cause the saine to explode at theProperttime to drive the rotary element, which foriconjyen- 5 ience Ishall hereinafter term the psto j It will -be apparentthat 'some featurSof the invention may be-einployed in r enginesA driven by expansivemediaAll than explosive niixtures,and I may e ploy the same in rotarysteam engines.

1- is -an annular shell providedwith a cylindrical bore -2 that extends4 entirel through the shell and provided in the wail of the bore with achannel 3 that is eccentric to the bore and Jforms a crescent-shapedcavit extending therearound approximate y 300 degrees more or ss,leaving an arched portion of the wal of the bore straight., .smooth and'uninterrupted from end to end ofthe shell. The bore 2 has par'- *allelWalls a, as clearly seen in Fig. 3, that .are unbroken except by thechannel 3 and ,by two annular channels 4, 5, which are arh 'fisy rangedto receive packing-rings 6, ,7, `t0 -inake a tight joint between therotaryhe'ad or piston S'and'the annular shell 1 toi revent escape of theexpansive medium a ong the face of the piston. Said piston Sliscylindrical and is constructed to forma close running fit with the walls.a of the openin 2v 'of the shell, and is provided with annu ar' which'is provided jivitl'i one or more radialV I'do not limit theinvetiwpn tothe exact form shown, norto the character of @cpan-.

ways 1.157 a radial way being provided for each ofthe gates'. Theperiphery of the ro- -'tary piston5 is-smchth, solid and unbrokeneirce'ptzat the mouths of'such. radial way or ways, each'of whichextends along vthe piston face a' distance corresponding to the width ofthe crescent-shaped channel 3 into which each gate iswadaptedto projectwhen the rc- 'ta'tion of. the pistonbring's it to that side of t leshell. The gates are duplicates, and the d ription of one applies toboth.

16 designates a spring to project thegate outward to engage the shelland to form a barrier across the crescent-shaped channel.

- looseness or wear.

The gate'comprises two relatively movable sections b and c, and awedge-shaped head 17 whereby the gate may expand to take up Said spring16 o crates upon the wedge-shaped head 17 to orce it Y outwardly to actupon the loose sections l), c,

of the gate 14 to press said sections toward the lateral walls of thechannel at the same time the gate presses against the peripheral AWallthereof to tightly close the'passage-way along the channel as the gatesmove therein.

19 designates a rotary valve at one edge of the smooth, uninterru tedarched wall and atx one end or tip of t e channel 3, and 20 designates apipe-to deliver compressed gas'or explosive mixture to the rotary valve19 which is provided with a ort 21 through which to receive the gas,and) through which to deliver the same or the roducts thereof, or both,to the tip of the c annel as the rotary valve 19 is turned on its axisfor that pur ose. '22 designates packing rings for sai rotary valve.

23 designates a s ring-actuated igniter in said rotary valve, t e samebeing arranged in any vwellknown manner to produce a spark inside thecavityjof the valve at an appropriate time when the port 21 is closed tothe supply-pipe 26, and 1s open or about to become open to the channel 3behind one of the gates 14.

24 is an adjustableblock mounted on the shell 1 and carrying a tripper25 for the dog 26 of the igniter. v

The valve 19 may able c ontrivance driven bythe rotation of the piston.In the drawings I have shown a cam 27 to which motion is imparted by theshaft 11, and which .cam engages a 'rod 28 y that actuates a crank 29against the force of spring 30, the tendency of which is to normallyhold the valve with its port 21 open to the, channel. f

31 designates an exhaust-port opening from the end ofthe channel 32 is avalve to close said exhaust-port. For the purpose of reversing theengine, the same is provided at"each end of the crescent channel withlike gas su ply, ignition and exhaust devices, the

be rotated byv any suitrotate.

.The spring 16 forces the gate outward to be expelled through theexhaust port 31.

connected 'with the levers 33, 33 by connect-.

ing rod 36, and controlled by the grip lever 37. -Said levers areconnected with the valves 32, 32, respect1vely, which alternately closeand open the exhaust ports, closing one at the sanieloperation thatopens the other. Said levers 33 are also connected with latch-rods 38,38", which are adapted to alternately hold out of commission the crank29 or 29', as the case may be, of the rotary valve which is to beclosed, and also holds said rotary valve closed,v at the saine timeallowing the other rotary valve to play freely, and allowing the spring30 to hold the cam-rod 28 thereof in position to be engaged by the cams27.

In practical operation, the levers 33 will be the different parts tooperate in a manner obvious from inspection of the drawings; that is tosay, the cam-27 actin(r on the rod. 28 will move the crank 29, theretbythrowing 'thrown into the position indicatedV in the v drawings, when itis 'desired to drive the pisthe valve 19 into position with the port 21adjacent the port or pipe 20 through which the com ressed gas or otherexplosive mebe admitted to thevalve. y

As-the piston rotates, the cam 27 passes the crankrod 28, thus allowingthe spring 30 to suddenly return the valve 19 into position Where itsport 21 will open into the tip of the channel 3. At the same instant, ora moment prior thereto, the igniter will be caused to operate to producea spark, thereby ig-A niting .the charge, whereupon the expansive-medium produced by the combustion of the gas will enter the tip of thechannel 3 just after the gate .14 has passed the port 21 so that thegate receives the impulse of the ex-V pansive force,` thereby causingthe piston to fill the-c iannel 3, and as the exhaust port 31 is openedto the atmosphere, the contents of' the gate 14 advances, the lrod 28and its crank 29 are again operated byfcam 27 to l upon .the operationjust described willl be repeated, vand .so on.

.37 lesignates a water-]acket through which vwater is circulated by thevalved pipes 39, 39.

40 designates valves to throttle or cut o':

the compressed J"gas supply. The levers 33 are preferably connected byrods 4l with the valves 40 to open the one and closev the other-v valve,and vice versa as the levers are thrown into one or the otherpositionfor driving or reversing the engine. vided With a-plurality ofnotches, as 42, .43',

the former being designed toholdtheflatch' that the piston is still.rotating i'n the direction indicated by; the large arrow in Fig. 2,:

the vcontents ofthe channel 3 will be retained insaid channel and willact as'a cushion to retard or prevent the advance of the gate 14. It isevident that the extent to which the-retard ation takes place willdepend largely upon the extent to which the exhaust port 3l is closed.the levers 33 may adjust them so as to throttle the exhaust to anyextent required, but such throttling only takes place when the gasvalves 40 have both been closed, and in any instance, When either of thegas valves 40 is open, the appropriate opposite exhaust-valve willllikewise 'be o )ened to allow free egress of the contents of t ile'channel 3 in advance of 4 4 1s a pet cock to draw oth any accumulation'sthat may occur in the channel 3.

and designate heads for'the shell removably secured by bolts 47.

The pistonprojects laterally beyond the sid'es of the channel 3 to formseats for a plnrality of spring packing-rings, as shown, in order tomake a gas-tight joint.

be-rofsnch rings may be employed as may be Any numfound necessary oradvisabl e.

The rings'and? are open, as shown at 43 in Fig. 4, and are compressibleinto the channels 9 and 10 therefor in the shell so as to allow thepiston to Sbe Withdrawnfrom the shell. 'In order to give A access to therings for contracting the same, each ofthe heads 45, 46, is providedwith a`-collai` 49, and the shell is recessed'to allow'said collarstolextend in- Ward'suliciently to -form the outer Walls of the channels4,'5, respectively.- l

50 designates set-screws in the piston adapted to be screwed in to clampthe gates when the same are compressed intoithe piston by the Wall ofthe shell oppositeA` the channel' When the .gates have' thus beenrclamped in thelpiston 'and vthe rings have' been contracted as stated,then the piston .may be Withdrawn and replaced as desired The segment 35is pro- The operator having control of :for repairs.' .After replacingthe -piston the set-screws'will be loosen ed, ythus to allow 'the gatesto freely move in their Ways as thel piston revolves.

. The inletjport 21 at one side and the exhaustport 31 at the other sideare spaced apartin one direction about two-thirds, and

cirilmference of the internal chamber of the shell, so' that the timeduring whichl the charge of hot-gases is held between the two gatesisreduced to the minimum, and the straight, smooth space between saidports f opposite the channel 3 is of maxi-'mum length t'o pack againstescape of -theggases in the wrong-direction. l
